To support kidney function in cases of chronic renal failure and to reduce oxalate stone formation. Kattovit Feline Diet - RENAL/KIDNEY was specially developed to provide cats with a reduced protein content by using high-quality protein in an easily digestible composition. High protein levels can be harmful to the kidneys. The key factor here is the protein content relative to the amount of energy. In Kattovit RENAL/KIDNEY, unlike conventional food, only about half of the energy comes from protein. Enrichment with potassium citrate alkalizes the urine and can thus prevent oxalate crystal formation (oxalate prophylaxis). The phosphorus and sodium levels are reduced.
